CULTIVATOR.

SPECIFICATION forming` part of Letters Patent No. 275,159, dated April3,1883.

l Application filed December 9, 1882. (No model.) A

`To all whom 'it may concern:

Be it known that I, EBER l?. DAVIS, a citizen of the United States,residing at Vitcherville, in the county of Sebastian and. State ofArkansas, have invented new and useful Improvements in Cultivators, ofwhich the following is a specification.

My invention is directed to the improvement of cultivator-plows adaptedfor use with a detachable shovel-carrying side bar.

My improvement embraces-a construction and combination in which the sideshovel-bar is braced directly from the main plow-standard and itshanger-brace `in such manner as to relieve the side projectingscrew-bolt, by which the side shovel-bar is adjustably secured to thebeam from the great force exerted upon the side shovel-carrying bar.This object is effected by a brace, which is secured at its lower end tothe main plow-standard and to its hanger-brace below the beam by thescrewbolt which fastens the brace, the main plowstandard, and itshanger-brace together, and at its upper end to the side projectingscrewbolt, so that the upward force exerted upon the sideshovel-carrying bar is borne by an upward pull upon said brace, and notby an upward force upon the side projecting screw, which would otherwisefail to carry the side shovel in proper relation to the main shovel. Inshovel-plows of this kind the side shovelcarrying bar has beenadjustably connected to the beam in various ways and supported by abrace connected to a bracket on the side u of the beam, in which theforce upon the side shovel-bar tends to bend the brace or break theconfining-screws of the side bracketin the same manner as it would tendto bend the side projecting screw. In shovel-plows of this kind the mainplow-standard has been formed ot' a bent strap pivoted tothe beam andadjustably combined with a hanger-brace, and it is with suc'hconstruction that I have combined the detachable side shovel-carryin gbar by a brace adapted for adjustment with the main plowstandard andsupporting the side shovel-bar Y by the hanger-brace rmly bolted to theunder side of the plow-beam, and by the main plow-standard bolted to thesides of the beam.4

The main shovel a is secured tothe lower end of a bar, 1),'forged of Uform, pivoted at its open end to the beam c by a bolt, d, passingthrough the ends ot' the bar b and secured by a nut, c. The shovel a issecured by a bolt, j', passing through between the bent bars and clampedby a nut, g, so thatthe shovel can be set down on the foot of the bar asit wears away.. A hanger, h, is bolted to the under side of the beam inposition between the bent bar, which is secured to it by a bolt, t',passing through both sides of said bar b and secured by a nut,j. Thishanger extends below the beam, near the middle ofthe length of said bar,and braces it against side strain.

The hanger is provided with two or more holes, a, whereby theshovel-carrying bar b can be set to run the shovel at more or less pitchby changing the bolt 1'., as shown by dotted lines in Fig. 4, the bentbar, in such adjustment, turning upon its beam securing bolt. The hangerextends in front and rear of the bent bar, and its connection with thelatter makes it a brace and a support for the main shovelcarrying bar.The hanger thus arranged serves to turn away the rubbish which might beotherwise collected upon the bent bar and choke the plow. The hanger hasstraight ends by which it is bolted to the beam, so that whilepractically forming a fixed standard for the shovelplow,is, in fact-,abeam attachment, serving the several purposes stated, and particularlyadapts an adjustable shovel-plow for use with an ordinary plow-beam. Thebeam is provided with a long screw-bolt, 7c, secured by nuts l l, so asto extend from one side in rear of the bent bar, and on the same side ahook, m, is secured to the beam near its front end, and the longscrew-bolt and the hook thus arranged adapt the beaml to receive asecond shovel-carrying bar, r, its front formed with an eye, by which tosecure it upon the hook m, and its rear end forming a curved standardfor the second shovel, s. This attachable second shovel-bar is securedto the long screwbolt b v nuts o o, so that it can be set nearer to orfarther from the beam-shovel. This second shovel-bar, however, could notbe so used IOO with the long beam-bolt but for the brace w, by which torelieve said long screwbolt from the great force and strain in plowing.The brace w for this purpose is secured to the bar r by the long bolt kand nuts o o, and to the plow-beam shovel-bar and to its supporting andbracing hanger by the bolt z'. This brace is provided with two or moreholes, 5v, to allow for the adjustment of the main shovel-bar to giveits shovel more or less pitch, as stated. The hanger It and the brace w,when both are used for a double-shovel plow, co-operate to connect,brace, and support both shovel-carry ing bars and allow of theiradjustment, as stated, and such construction and arrangement forms anovel means whereby a single or double shovel is used with the ordinaryplowbeam provided with handles and a clevis.

I claiml. rJhe combination, in a shovel-plow, ofthe pivotedbeam-standard b and its hanger-brace h with the side shovel-carryingbar, r, the side projecting screw-bolt, k, nuts v e, the brace fw, andthe screw-bolt i, the said brace being secured to the plow-standard band to its hangz5 er-brace below the beam, and to the screw-bolt 7c,passing through the beam, substantially as described, for the purposespecified.

2. In combination with the plow-beam provided with the side hook, m, andthe hanger- 3o braceh, of the plow-standard b, the side shovelbar, r,the screw-bolt 7c, nuts t fu, andthe brace fw, said brace being securedto the screw-bolt 7c, to the plow-standard Z1, and to the hangerbrace,and adapted for adjustment with plow- 35 standard, substantially asdescribed, for the purpose specied.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing wit,` nesses.

EBER P. DAVIS.
